Patent TW-425579-B (TW)
Title: Integral thin-film metal resistor with improved tolerance and simplified processing
Inventor: DUNN GREGORY J
IPC: H05K3/06
Filed: 1999-07-13
Granted: 2001-03-11
Abstract: A method for manufacturing a microelectronic assembly to have a resistor (12), and particularly a metal resistive film (14), with desirable processing and dimensional characteristics. The method generally entails applying a photosensitive dielectric to a substrate (18) to form a dielectric layer (20). The dielectric layer is photoimaged to polymerize a first portion (22) of the dielectric layer on a first region of the substrate, leaving the remainder (24) of the dielectric layer unpolymerized. An electrically resistive film (28) is then applied to the dielectric layer, and the dielectric layer is developed to remove concurrently the unpolymerized portion thereof and the portion of the resistive film overlying the unpolymerized portion, so that a portion of the resistive film remains over the second portion to form the resistor. An alternative process order is to apply the resistive film prior to exposing the dielectric layer to radiation, and then exposing the dielectric layer through the resistive film. The resistive film is preferably a multilayer film that includes an electrically resistive layer (28), such as NiP, NiCr or another nickel-containing alloy, and a sacrificial backing (30) 2such as a layer of copper.

Title: Formation of metallic contact
Inventor: TAN WEN-YI
IPC: H01L21/768
Filed: 1999-09-17
Granted: 2001-04-11
Abstract: A method for forming metallic contact is disclosed. After the metal plug is formed in the contact, a over etching step is proceeded to remove a part of the metal plug and form a concave in the contact. Then spacer is formed on the sidewall of the concave. Via this spacer, the opening size of the top of the contact is shrunk and so that the photolithography and etch processes on the metal line upon the contact can be proceeded easily. Furthermore, due to the larger distance from the neighboring contact to metal line, the short circuiting resulted from two metal lines too close is prevented.

Title: Detecting circuit for rotating speed of electric fan
Inventor: CHEN HUNG-HSIANG
Filed: 1999-09-20
Granted: 2001-09-21
Abstract: The present invention provides a kind of detection circuit for detecting the rotating speed of the electric fan. The electric fan contains an output terminal used to output a rotation signal, in which the cycle of the rotation signal is inversely proportional to the rotating speed of electric fan. The detecting circuit contains at least one pulse generator, which is electrically connected with the output terminal of the electric fan and is used to generate a delay pulse with a predetermined cycle, and a detector, which is used to detect the delay pulse generated by the pulse generator and generate a detection signal of rotation speed when the delay pulse generates waveform variations. Each rotation signal output by the electric fan can make the pulse generator generate a delay signal with a predetermined cycle. When the electric fan continuously outputs a plurality of rotation signals, if the cycle of each rotation signal is smaller than the predetermined cycle of the delay pulse, the cycle of the corresponding delay pulse output by the pulse generator can be extended continuously so as to make the pulse generator generate no variation of output waveform. When the cycle of an arbitrary rotation signal output by the electric fan is larger than the predetermined cycle of the delay pulse, the cycle of the corresponding delay pulse output by the pulse generator will not be extended so as to make the pulse generator generate output waveform variation.

Granted: 2002-08-21
Abstract: An interlayer insulating film (21) is formed on a substrate (1), and a polysilicon layer (10) is formed on the interlayer insulating film (21). An interlayer insulating film (22) is formed to cover the polysilicon layer (10), and a polysilicon layer (11) is formed on the interlayer insulating film (22). An interlayer insulating film (23) is formed to cover the interlayer insulating film (22). A hole (20M) for a mark to constitute an alignment mark or the like is formed from a surface (23S) of the interlayer insulating film (23) to the polysilicon layer (11). The hole (20M) for a mark is larger than a contact hole formed from the surface (23S) to the substrate (1) but is shallower than the contact hole. Consequently, a concave portion corresponding to the hole (20M) for a mark is formed, with difficulty, on a silicon oxide layer to be subjected to CMP polishing and then become an interlayer insulting film (4). Therefore, it is possible to prevent a slurry from remaining in the concave portion. Thus, it is possible to obtain a semiconductor device having high reliability without a disadvantage such as a wiring disconnection or the like which is caused by the remaining or scattering of the slurry to be used for a CMP method.
